A kg ball moving at 6 m/s the + x-axis makes a glancing collision with a 3 kg ball initially at rest . After the collision , the kg ball is moving at 3 m/s at an angle of - - 40 degrees . Find the speed and direction of the 3 kg ball​

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
